Plasma Spectroscopy Lead

Commonwealth Fusion Systems (CFS) has the fastest, lowest cost path to commercial fusion energy. 

CFS is collaborating with MIT to leverage decades of research combined with new groundbreaking high-temperature superconducting (HTS) magnet technology. HTS magnets will enable compact fusion power plants that can be constructed faster and at lower cost. 

The mission is to deploy fusion power plants to meet global decarbonization goals as fast as possible. CFS has assembled a team of leaders in tough tech, fusion science, and manufacturing with a track record of rapid execution. Supported by the world’s leading investors, CFS is uniquely positioned to deliver limitless, clean, fusion power to combat climate change.

Commonwealth Fusion Systems (CFS) has the fastest, lowest cost path to commercial fusion energy.

CFS collaborates with MIT to leverage decades of research combined with groundbreaking new high-temperature superconducting (HTS) magnet technology. HTS magnets will enable compact fusion power plants that can be constructed faster and at lower cost. Our mission is to deploy these power plants to meet global decarbonization goals as fast as possible. To that end, CFS has assembled a team of leaders in tough tech, fusion science, and manufacturing with a track record of rapid execution. Supported by the world’s leading investors, CFS is uniquely positioned to deliver limitless, clean, fusion power to combat climate change. To implement this plan, we are looking to add dedicated people to the team who treat people well, improve our work by adding multifaceted perspectives and new ways of solving problems, have achieved outstanding results through a range of pursuits, and have skills and experience related to this role.

CFS is looking to grow the SPARC Diagnostics team with a specialization on instruments that analyze UV, visible and infrared light to interpret high temperature plasmas. Applications will include both real-time plasma control and improving scientific understanding of burning plasma physics, with tools including camera, filter and grating based instruments Conceptual design of the spectroscopy diagnostics has been completed and CFS is looking for candidates to lead more detailed system design and shepherd instruments through fabrication, assembly, calibration, commissioning and utilization. For early operations, SPARC plans to field systems to distinguish between isotopes of helium and hydrogen to control fueling, fast filterscopes and grating spectrometers to measure fuel and weakly ionized impurities, and filtered camera systems in the visible and infrared. These tools will mostly be deployed in a remote diagnostic laboratory space next to the tokamak hall. Candidates will work closely with the Optical Imaging Lead who’s role will focus on design and deployment of light extraction and relay optics in port-plugs and the tokamak hall. Further enhancements are also envisioned over SPARC’s operational life that leverage techniques demonstrated on existing tokamaks. Candidates will work as part of an integrated diagnostic and operations team that includes MIT-PSFC partners and fusion community collaborators from around the world.

CFS team members thrive in a fast-paced, dynamic environment and have demonstrated exceptional results through a range of different pursuits. We all tightly align with our company values of integrity, execution, impact and self-critique. As we grow, we are looking to add talented people who are mission driven and bring diverse perspectives and new ways of solving problems.
